Astragalus fruit has the effects of promoting digestion, invigorating stomach, moistening lung and relieving cough, resolving phlegm and regulating qi. Black Huangpi sapling, also known as Guangxi Huangpi, is a new variety produced in Huang Wu Village, Baishishui Town, Pubei County, Guangxi.

After the development of wampee seedlings, black wampee became the main fruit for local farmers to grow rich. Next, I will explain in detail the management methods of black and yellow saplings in Guangxi:

1. Cultivate robust fruiting mother branches. Fruits should be fertilized first, and topdressing should be done in time during the growth and development of autumn shoots of black and yellow skin seedlings to promote the timely germination and vigorous growth of fruiting mother branches.

2. Pruning of black and yellow skin seedlings in the growing season: combining fruit picking or timely retracting or cutting off fruiting mother branches after fruit picking, the management of black and yellow skin seedlings promotes autumn shoots and cultivates strong fruiting mother branches.

3. Management pruning of black and yellow bark seedlings in winter: combined with clearing gardens in winter, it is mainly to cut off dead branches, pests and diseases, shady branches and weak branches of black and yellow bark seedlings to ensure ventilation and light transmission of trees.
